Constructor Details

AbstractFlattenLastNode

protected AbstractFlattenLastNode(int flattenLastStoreIndex,
 Function<EffectiveItem_,Iterable<FlattenedItem_>> mappingFunction,
 TupleLifecycle<OutTuple_> nextNodesTupleLifecycle)

Method Details

insert

public final void insert(InTuple_ tuple)

Specified by:

insert in interface TupleLifecycle<InTuple_ extends AbstractTuple>

createTuple

protected abstract OutTuple_ createTuple(InTuple_ originalTuple,
 FlattenedItem_ item)

update

public final void update(InTuple_ tuple)

Specified by:

update in interface TupleLifecycle<InTuple_ extends AbstractTuple>

getEffectiveFactIn

protected abstract EffectiveItem_ getEffectiveFactIn(InTuple_ tuple)

getEffectiveFactOut

protected abstract FlattenedItem_ getEffectiveFactOut(OutTuple_ outTuple)

retract

public final void retract(InTuple_ tuple)

Specified by:

retract in interface TupleLifecycle<InTuple_ extends AbstractTuple>

getPropagator

public Propagator getPropagator()

Description copied from class: AbstractNode

Instead of calling the propagation directly from here, we export the propagation queue and allow BavetConstraintSession to call it. This is done with the idea that Propagator only has two implementations (unlike AbstractNode with myriad implementations) and therefore JVM call site optimizations will kick in to make the method dispatch faster.

Specified by:

getPropagator in class AbstractNode

Returns:

never null; the PropagationQueue in use by this node
